GEORGE C. IBEIDLER, OF ROCHESTER, NEW YORK.

PHOTOGRAPHING APPARATUS.

Application filed November 2. 1911.

To all whom 2'25 may concern:

Be it known that I, GEORGE C. BEIDLER, a citizen of the United States of America, and resident of ltochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Photographing Apparatus, of which the following is a specification.

. This invention relates to photographing and developing apparatus and particularly to means for immersing photographic films in a liquid which is provided for acting on the coated surfaces of the films. n

An object of this, invention is to provide novel means for immersing a film after it has been delivered to a receptacle, the present embodiment of the invention being as sociated with a receptacle designed to contatin hypoor fixing fluid. It is to be understood however that the receptacle with which the immersing device is associated may contain any liquid adapted to act on the coated surface of the film or it may be water used to rinse or wash the film.

A further object of the present invention is to provide means for elevating and releasing the immersing frame, novel means being provided for controlling the descent of the said frame within the receptacle, the said controlling means allowing a gradual descent of the said immersing frame in the receptacle. It has been found in practice that where an immersing frame is elevated and then released and allowed to descend by gravity. unrestricted, the said frame splashes, the liquid in the receptacle to such an extent as to be objectionable and therefore the present invention is directed to control the descent of the said frame, the same being associated with and connected to the frame orv operating mechanism thereof.

lVith'the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, ref erence will be had to the accompanying drawings forming part of this specification Specification of Letters Patent.

Patented Oct. 5, 1915. Serial No. 658,178.

wherein like characters denote correspond ing parts in the several views, and in which- Figure 1 illustrates a view in side elevation of a photographing and developing apparatus with the power applying element omitted in order to more fully show the immersing frame and its operating mechanism; Fig. 2 illustrates a perspective view of a fragment of the casing of the photographing and developing apparatus with a fragment of the immersing apparatus applied; Fig. 3 illustrates a sectional view takenap-v proximately centrally of Fig. 2 of a fragment of the casing with the immersing device in longitudinal section; Fig. 4 illustrates a sectional view of a pneumatic cushion utilized in connection with the immerse ing frame; Fig. 5 illustrates an enlarged detail view in section of a fragment of the piston rod of the cushioning device more fully showing the control of a port for regulating the action of the cushioning device; Fig. 6 illustrates a perspective view of a combined link arm and finger; and Fig. 7 illustrates a sectional view of the bracket and a bearing thereon associated with parts of the apparatus. Fig. 8 illustrates the details of mechanism for operating the immersing frame.

In these drawings 10 denotes a casing of a photographing and developing apparatus, provided witha camera 11 and other elements necessary to the formation of a photo graphing and developing apparatus which will notbe described in detail. It is suflicient, it is believed, for a disclosure of the tostate that films are eX-' present invention posed to the action of light and are carried through the casing 10 and delivered to the.

receptacle 12 which is adapted to contain fluid which will act on the coated surface of the film. As the apparatusis now used, the said receptacle 12 contains hypo or fixing fluid and the vfilm, after being developed and delivered to the receptacle 12 is subjected to the action. of said fixing fluid-- Difficulty has been film in its wet state experienced in delivering after being developed,

to the fixing solution, yet maintaining the said film in an uncrumpled, unfolded, or uncreased state to the liquid within the receptacle 12. To overcome the difiiculties just stated provision has been made for spreading the film over the surface of the liquid Within the receptacle 12 prior to its being released therein. To accomplish the result just indicated, that is to say, of spreading the film, spreading fingers 13 have been mounted in brackets lt so as to be oscillatable with relation to the receptacle 12, the said fingers 13 being operated by the arm 15 whlch is actuated from the gear wheel 16 in any appropriate way.

The gear wheel 16 is driven by the pinion A, which pinion is rotated in any suitable manner and the gear wheel 16 has a cam 17 on its face engaged by the lug 18 on the arm 19 so that as the cam 17 is rotated, the arm 19 ascends and descends under the control of the cam. The arm 19 has pivotally connected to it, the links 20 and 20 which links are mounted on shafts 21 journaled in the brackets 22 which have their bases 23 anchored to the casing 10. While I have referred to the brackets 22 in the plural, it is to be understood that a duplicate of the bracket shown in Fig. 1 is provided on the opposite side of the receptacle 12 and a view thereof is prevented by the intervention of the elements appearing in elevation in Fig. 1.

The shafts 21 are carried by the cranks 24- which shafts oscillate in bearings 24:" formed integral with the brackets 22. The cranks 24: are connected to lugs 25 of the immersing frame 26 so that as the arms of the cranks 24L oscillate, the frame 26 ascends and descends with relation to the receptacle 12 and as they descend within the receptacle 12, a film which has been spread in the receptacle and is supported by the liquid contents thereof is immersed in the said liquid contents by a downward and longitudinal movement of the frame. The movement thus given the frame and the film results in dis? lodging air bubbles from the under surface of the film and allows access of the liquid contents of the receptacle to the treated surface of the film.

In order to prevent splashing of the liquid contents of the receptacle by the too rapid descent of the frame, one ofthe links 20 has an arm 27 to which there is pivotally connected a hollow piston rod 28, the said hollow piston rod extending into the head 29 of a cylinder 30. The hollow piston rod extends through a piston 31 within the cylinder and upon inward movement of the piston within the cylinder, air compressed by the cylinder escapes through thehollow piston rod and through a port 31 which is provided in the said piston rod. In order to control the escape of air through the piston rod, the port is guarded by a screw 32 having a tapered side 33 in order that the port opening may be increased or diminished according to the adjustment of the screw 32. It is apparent from an inspection of Fig. 5 that the port opening will be diminished as the screw descends into the port and vice versa. In order to permit a slight oscillation of the cylinder to accommodate the movement of the arm 27, the said cylinder has an arm 34 hinged to a plate 35 which is secured to the casing 10, so that as the arm 27 oscillates, the cylinder may be likewise oscillated.

The combined link 20 and arm 27 has an integral finger 36 extending rearwardly within reach of an operator in order that the frame may be manually operated or elevated out of the receptacle when the film is to be inspected or for other purposes.

From what has been stated and by reference to the drawing, it will, it is thought, he observed that the gear wheel 16, operating as it does, communicates motion to the cam 17 and operates the arm 19 which actuates the immersing frame. The gear wheel 16 is further provided with a side cam B which actuates the arm 15, Which arm actuates the mechanism to which the spreading fingers are operatively connected, the relation being such that the recess in the cam 17 is in position to allow the arm 19 to descend. thus ermitting the descent of the immersing frame at a time when the widest part of the cam B is engaged by the arm 15 for holding the spreader fingers approximately parallel with the arm 19 or in their open position, to which position they have traveled to spread the film in the receptacle 12, so that when the immersing frame descends in the receptacle 12, it may carry the spread film into the liquid contained therein. Just prior to the elevation of the arm 19 by the cam 17, the arm 15 is released by the cam B and the spreading fingers are moved inwardly under the influence of the actuating mechanism provided for said fingers.

While I have, in the present application, described and shown an immersing frame and means for spreading film over the surface of the liquid within the receptacle, and

have furthermore shownmeans for operating the immersed frame, also means for operating the film spreading means from a driven shaft, the claims in the present application are not directed to those features, but those features constitute part of the subjects matter of other applications for patent filed by me, one of said applications having been filed January 3, 1910, and numbered 535,939, and another of saidapplications bearing date of May 20, 1911, and Serial No. 628,415.
